To aZZ whom, z5 'mag/concern.'

Be it known that I, HENRYPARsONsof Waterloo, in the county of Seneca and State of New York, have invented certain new and useful improvements in Harnesses for Lopms; and I do hereby declare that the following` is a full and exact description thereof, reference being had to the accompanying drawings,

.making part of this speciiieation. perspective view of my irn- Figure l is a proved harness, looking on the rear side; Fig.l 2, a vertical section of one end thereof in the plane indicated by the line a: x, Fig. 1;

Fig. 3, a perspective view of one cornerof-the same, looking on the front side, and showing the Lend of the heddle-bar removed from its mortise.

Like letters designate corresponding parts -in all the figures.

It is the object of my improvements to secure the heddle-bars in their iframe Vin such a manner as to he easily removable, but at'the same time to be firmly retained in place when in use.

The ordinary rectangular frame,A,is used, in which are mounted the heddle-bars B B, as usual, having strung on them theheddles, as indicated by red lines in Fig. l. 'The ends of the heddle-bars rest in mortises ar, a made in the side or end' pieces of the frame,and are secured in place as follows: On one of theside or end pieces of the frame arc'situated two plain dat springs, C C, usually made of steel and. sunk Hush with the Wood, andv securediat one end. by screws b I, while thelother or elustie end rests-over the extremity of the h'eddle- I bnr, fitting in its socket or mortise.` In'this end of euch spring is made a pin, c, Figs, 2 and 3, the spri ngnsnflieientdistance to reach through the side ot' the fra1ne,fh 1sh, or about' so, with; its opposite surlhce, biit'not beyond it.r

These pins beeomeloose'" from. wear and motion and frequently drop I out or project so as to interfere with the vertical movement of the harnesses, andare thus the source of much difculty. By being driven in closely they are also troublesome torenove when the heddle-bars areto be taken fronrthie frame. By the use of my arrangement above described these di'iculties are avoided. The` v 15% force o f the springs always keeps thel bars in' f place in the most violent motion of the'harness.- The parts all being flush with the frame, allowIv the harnesses of a loom to work in eontac'twith each other without interference, :andthe .lied-fdie-bars are expeditiously removed by merely pressing on the end of the pin c and bendingr back the spring. ff The oppositerends'- ofthe heddlebarsrest likewise in the opposite side.y 'or end .piece'o thefrarne and have cut Aontheirextremities; outside the frame, screw-threadsgg,on2lwi1iel E screw square nuts h It, asrepresented in-fFig, kvl By means offthese nuts. the heddle-bars1iar straightened ,or tightened in place,so;;that thier th'ezviolent action of theharness these nntsjai them in place. o securely retainthennlatl tach springs G G, with square ends and substan@ tially o'f theforin represented7 tothe 'end piecel ofthe frame, the springs springingeontwar ively,aga"!st one side ofthenuts,-andth'ereby` preventjtheiry turni-ing.'` 'Whenfthefnntsnre'to' .ljefvtn'rnedhe springs :are sprnn-gontward or 'pressed'in away from'.eontact.V 1-1 .The heddlfbarsmaybe stilcnedorbraced centrz'rlly by'I ooksor supports i i, or in any' ldesirable manner. q
